Jean-Michel Basquiat (December 22, 1960 – August 12, 1988) was an American artist. He first achieved notoriety as part of SAMO, an informal graffiti duo who wrote enigmatic epigrams in the cultural hotbed of the Lower East Side of Manhattan during the late 1970s where the hip hop, post-punk, and street art movements had coalesced. By the 1980s, he was exhibiting his neo-expressionist paintings in galleries and museums internationally. The Whitney Museum of American Art held a retrospective of his art in 1992.

homage to Keith Haring.
Keith Allen Haring (May 4, 1958 – February 16, 1990) was an American artist and social activist whose work responded to the New York City street culture of the 1980s by expressing concepts of birth, death, sexuality, and war. Haring’s work was often heavily political and his imagery has become a widely recognized visual language of the 20th century.
